There is an excellent article about primers on the Shooting Times website. We strongly recommend you read Mysteries And Misconceptions Of The All-Important Primer, written by Allan Jones. Mr. Jones is a bona fide expert — he served as the manager of technical publications for CCI Ammunition and Speer Bullets and Jones authored three editions of the Speer Reloading Manual.

This authoritative Shooting Times article explains the fine points of primer design and construction. Jones also reveals some little-known facts about primers and he corrects common misconceptions. Here are some highlights from the article:

Size Matters
Useful Trivia — even though Small Rifle and Small Pistol primer pockets share the same depth specification, Large Rifle and Large Pistol primers do not. The standard pocket for a Large Pistol primer is somewhat shallower than its Large Rifle counterpart, specifically, 0.008 to 0.009 inch less.

Magnum Primers
There are two ways to make a Magnum primer — either use more of the standard chemical mix to provide a longer-burning flame or change the mix to one with more aggressive burn characteristics. Prior to 1989, CCI used the first option in Magnum Rifle primers. After that, we switched to a mix optimized for spherical propellants that produced a 24% increase in flame temperature and a 16% boost in gas volume.

Foiled Again
Most component primers have a little disk of paper between the anvil and the priming mix. It is called “foil paper” not because it’s made of foil but because it replaces the true metal foil used to seal early percussion caps. The reason this little disk exists is strictly a manufacturing convenience. Wet primer pellets are smaller than the inside diameter of the cup when inserted and must be compacted to achieve their proper diameter and height. Without the foil paper, the wet mix would stick to the compaction pins and jam up the assembly process.

Review by Tom Gresham, Gun Talk Radio Host
“At some point, every gun owner asks the question, ‘What’s it worth?’ The leading reference for decades has been the Blue Book of Gun Values. Whether you are a seller, a buyer, a shopper, or just curious, this constantly-updated gold mine of research is your friend.”

High Power and F-Class shooters have a ton of gear they need to carry out to the firing lines. To do the hauling, you can certainly purchase a factory-made, purpose-built cart that folds up and has all the bells and whistles. The Creedmoor Sports CRC-1 (photo right) is a proven, quality product that works great. You’ll find these used by top shooters at Camp Perry. But the Creedmoor CRC-1 cart costs $499.95.

For a fraction of that price ($54.99), plus a few dollars more for do-it-yourself enhancements, you can have a heavy-duty cart that will haul all your gear just fine, though it doesn’t fold up. In the top photo is a Harbor Freight Welding Cart we saw at the Berger Southwest Nationals. This rig is carrying a rifle in hard gun case, bipod, folding chair, shooting mat, tripod, spotting scope, rear sand-bag, and ammo box — that’s a lot of gear!

Check out the Harbor Freight Welding Cart, item #65939. This cart is ON SALE right now for just $54.99. Overall size is 29-1/2″ L x 20″ W x 49″ H, and width between side rails is 18″. The wheels (with tires) are 20 3/4″ in diameter for smooth rolling. Consider that, if you made your own cart from scratch you could easily pay $30.00 or more just for the large-diameter wheels and axle. Do note — this cart has air-filled tires. Be sure to inflate before you go to the Range!

As sold, the Harbor Freight Welding Cart can benefit from upgrades for range use. But with a few bungee cords (and some creativity), the cart can be adapted pretty easily to hauling your gun gear. If you want to enhance the basic cart, it’s easy to add plastic side-panels on the bottom unit, and fit a barrel-holding system on the cross-tube. This ensures rifles and gear won’t flop forward. (A small piece of wood under the bottom panel provides a bit of extra lift that will keep the bottom plate out of the dirt and gravel.)
